Problems solved by technology

The above-mentioned measures need to be completed in the design stage. Once the construction of the heating furnace is completed, the implementation of these measures must increase equipment investment
[0005] (2) In addition to reducing the "black mark" of the water beam by optimizing the equipment, the "black mark" can also be reduced by increasing the furnace temperature to stre

Example Embodiment

[0027] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0028] Figure 1~3 The working state of the steel billet shown on the water beam of the heating furnace in the walking beam heating furnace has been described in detail in the background art, and will not be repeated here.

[0029] The method for reducing the black mark of the billet water beam of the walking beam heating furnace designed by the present invention includes the following steps:

[0030] Step 1: Control the pusher to push the billet 6 onto the water beam of the heating furnace of the walking beam heating furnace. The heating furnace water beam includes a fixed beam 7 and a walking beam 8, and a fixed beam 7 and a walking beam 8 There is a cushion block 1 on it;

[0031] Step 2: Adjust the horizontal stepping stroke of the walking beam 8 in the water beam of the heating furnace to n(L d +L s )+L d , Where n is a natural number (0, 1, 2, 3...),...

Abstract

The invention discloses a method for decreasing a walking beam heating furnace steel billet water beam black mark. The method comprises the steps of: 1) controlling a steel pusher in terms of pushing a steel billet onto a heating furnace water beam of a walking beam type heating furnace, with the heating furnace water beam composed of fixed beams and walking beams; 2) adjusting the horizontal walking stroke of the walking beams in the heating furnace to n(Ld+Ls)+Ld; and 3) heating the steel billet in the walking beam type heating furnace, and delivering the steel billet to a walking beam type heating furnace outlet by the heating furnace water beam according to the horizontal walking stroke of n(Ld+Ls)+Ld. With the method provided in the invention, under the precondition of not changing equipment and a heating process, the contact time of a same position on the steel billet and heel blocks can be decreased only by reasonably arranging the length of the water beam heel blocks, the space between the heel blocks and the water beam walking stroke, thus reaching the purpose of mitigating the water beam black mark.

Description

technical field [0001] The invention relates to the technical field of billet heating in a heating furnace, in particular to a method for reducing black marks on billet water beams in a walking beam heating furnace. Background technique [0002] At present, the running state of the steel billet on the water beam of the heating furnace in the walking beam heating furnace is as follows: Figure 1~3 As shown: the outer periphery of the cooling water pipe 4 of the water beam of the heating furnace is covered with the water beam refractory material 3, the steel billet 6 is directly in contact with the cushion block 1 on the cooling water pipe 4 of the water beam of the heating furnace, and the cushion block gap 2 is formed between the adjacent cushion blocks 1. Since the cooling water pipe 4 is filled with steam-water mixture 5 or water vapor, the surface temperature of the pad 1 placed on the cooling water pipe 4 is relatively low. In addition, the shielding effect of the cooling...
